...this is especially true for n-dimensional cell arrays. In MATLAB, for example, I could generate a (say) 2x2 cell array using test={A B;C D} The only way I can figure out how to do this in R is using something like test=list(A,B,C,D); dim(test) < c(2,2); This seems to work, but defaults to bycolumn (in other words, instead of A B C D I get A C B D ) So, I follow with test=t(test) as needed to flip the thing around to byrow. OK, so the question is - is there a better way? This *seems* to work, but I'm discovering that R is a lot like working with LaTeX (something I know muc...

...ave read on reorder()makes any sense to me at all. Can anyone help? Also, not to get snippy, but it seems to me that a very obvious and useful flag for the contourplot() function would be some sort of order flag, which could take arguments like "reverse" or "byrow" or "bycolumn". As far as I can tell, nothing of the sort exists. Am I right about this? If so, why is this the case? A flag in a function would be a much more convenient way of changing plotting order than actually messing around with your data. Thanks. [[alternative HTML version deleted]]

Hi, layout(1:2) # split the screen into 2 regions plot(1:2) # plot in region 1 plot(1:2) # plot in region 2 par(mfg=c(1,1)) # Then I want to update the plot in region 1 plot(1.5,1.5) But the this last plot overlays with my 1st plot. Q: How do I replace my first plot with my last? #### NOTE ###### I know I can do this with split.screen and screen(n,TRUE) But then it actually clears the
